Regarding the characteristics, engineering needs and technical difficulties of the Chuhe Bridge of the Hening Expressway Project, relying on the four-to-eight expansion project of the Hening Expressway, combined with modern information technologies such as BIM, big data, cloud computing, mobile Internet, etc. Virtual simulation and other technologies can solve the technical problems in the construction of expressway expansion projects, and directly serve the expansion project of Hening Expressway.

Abstract. With the contradiction between construction design and natural environment has become increasingly fierce, the sustainable development theory has become inevitable trend of construction development on account of comparing now living needs and long-term survival needs. BIM technology think of standardization, integration, intellectualization as target, it can provide an accurate, efficient, integrated and intelligent design platform. So it break through the limitations of traditional design rule on expressive methods, fully expresses the designer's design concept, improves the investment benefit, realizes the goal of building energy efficiency, eventually, promotes sustainable development of construction design.
